摘要：

A　new　solar　energy-phase　change　storage-floor　radiant　heating　system　is　proposed　to　provide　a　comfort　indoor　environment　in　winter.　In　this　study　the　proposed　new　system　is　applied　in　an　office　building　in　Urumqi　in　China.　The　system　consists　mainly　of　three　units:　evacuate　heat　pipe　solar　collectors　(as　heat　collection　unit),　vertical　phase　change　thermal　energy　storage　device　(VPCTESD)　and　floor　radiant　heating　system.　The　influence　on　thermal　efficiency　of　solar　collector,　inlet　and　outlet　water　temperature,　connect　method　during　local　heating　period　and　thermal　performance　of　this　system　was　developed　experimentally.　The　results　reported　in　this　paper　adequately　support　the　new　system　as　an　alternative　to　the　traditional　solar　heating　system,　and　it　can　increase　30%　utilization　of　solar　energy　than　traditional　solar　heating　system.　The　research　result　provides　a　reference　for　optimization　design　of　this　kind　of　system.　©　2016　The　Authors.　Published　by　Elsevier　Ltd.
